Abstract
A catalytic unit for treating gases, particularly exhaust gases of internal combustion engines, comprising a housing, adapted to be connected in an exhaust gas line, and a monolithic carrier body provided with a catalytic agent. The carrier body is mounted within the housing by an intermediate layer arranged in compression between the circumferential surface of the carrier body and the housing. The intermediate layer is so compressed by the surrounding housing that it exerts a pressure on the surface of the carrier body in the range of 20 to 80 N/cm.sup.2.
